Limbal Stem Cell Transplantation(Sun Yat-sen University)

Corneal disease is a leading cause of blindness in the world. A shortage of corneal donor tissue has prevented many patients from regaining vision. Additionally, refractive error such as myopia is a major cause of impaired visual function worldwide. Although refractive error is correctable by procedures that modify the refractive power of the cornea, these procedures often weaken corneal integrity and have risk of complications. This study aims to evaluate the safety and efficacy of corneal surface epithelium repair and regeneration in the treatment of corneal surface diseases and refractive error using autologous limbal stem cell transplantation.
